perf_counter: tools: Expand the COMM,MMAP event synthesizer
Include code to pre-construct mappings based on /proc, on system wide recording. Fix the existing code to properly fill out ->pid and ->tid. The PID should be the Thread Group ID (PIDTYPE_PID of task->group_leader) The TID should be the Thread ID (PIDTYPE_PID of task) Furthermore, change the default sorting of report to comm,dso for a better quick overview.
